T foil control systems
« on: May 09, 2020, 05:08:24 PM »
Most cherubs seem to be set up so you pull the rope to pull more t foil on.

Is there a reason why they aren't set up the opposite way around to pull the rope to take t foil off?
If in doubt flat out

It is possible for a T-foil to come on by itself if the lift is well infront of the hinge axis. I did this by acsident. It was a little unnerving to suddenly get some extra lift. It did stall quickly but wasn't fun, and was modified before the next sail.

We had  this with ronin, i would not advise a system that relies on it, as Phil says it stalls and does not stay put, the last thing you want when you are bouncing down big waves is an unexpected lifting of the stern!!! it actually cost us a pursuit race once as we were dragging the bow while coming up fast on the stern of a laser, we passed them within a second or two of crossing the line but this is a very extreme case, we fixed it soon after that!!!

For the control system? No reason why not.

Important bit is that the foils stays where you want it (see posts above). Most foils want to release, so you pull to add more. If you have a major bungee or a definite position system - then fine
